List of products by brand H&K

Heckler & Koch (H&K) is a legendary German firearms manufacturer renowned for its "No Compromise" approach to engineering, creating some of the most reliable, durable, and iconic firearms in modern history. The company is synonymous with elite special forces and counter-terrorism units worldwide, who have famously used the MP5 submachine gun. H&K's product line includes the HK416 rifle (a standard for many NATO special forces), the G3 battle rifle, and a highly respected line of polymer-framed pistols like the USP and the modern VP9.

Founded in 1949 in Oberndorf, Germany, by former Mauser engineers Edmund Heckler, Theodor Koch, and Alex Seidel, Heckler & Koch rose from a post-war machine tool manufacturer to become one of the most respected and influential small-arms designers in the world.

H&K's early reputation was built on its mastery of the roller-delayed blowback operating system. This robust, reliable, and inherently accurate mechanism was the heart of its first major success, the G3 battle rifle, which was adopted by the German Bundeswehr and over 60 other nations. This same system was then scaled down to create the MP5 submachine gun in the 1960s. The MP5's combination of a closed-bolt, roller-delayed action (making it far more accurate than open-bolt SMGs) and its legendary reliability made it the definitive choice for police and counter-terrorism teams for over three decades, including the British SAS.

H&K has also been a major innovator in pistol design. They were one of the first to market with a polymer-framed pistol (the VP70 in 1970) and a squeeze-cocking pistol (the P7). Their breakout success in the 1990s was the USP (Universal Self-loading Pistol), a rugged, hammer-fired service weapon that became the foundation for the legendary Mark 23 (MK23), a massive .45 ACP "offensive" pistol built to extreme specifications for U.S. Special Operations Command (SOCOM).

In the 2000s, H&K developed the HK416, a short-stroke gas piston rifle based on the AR-15 platform. It was designed to dramatically improve the reliability of the M4 carbine, and it has since been adopted by many of the world's most elite units, including the U.S. Marine Corps as the M27 IAR. Today, their VP9 striker-fired pistol is a major competitor in the civilian and law enforcement markets, known for its superb ergonomics.
